Why tRNA is called soluble rna?

tRNA or Transfer Ribonucleic acid which transfers the amino acid to mRNA and acts as connecting link between them. Also the tRNA is known as the soluble RNA as they are soluble in 1M-Nacl. Hence they are also known as soluble RNA. read more

Soluble RNA was originally called this because a soluble segment of RNA from liver cells that did not sediment (settle at the bottom/come out of suspension) after several hours of centrifuging lead to the discovery of this type of RNA. read more

A transfer RNA (abbreviated tRNA and formerly referred to as sRNA, for soluble RNA) is an adaptor molecule composed of RNA, typically 76 to 90 nucleotides in length, that serves as the physical link between the mRNA and the amino acid sequence of proteins. tRNA does this by carrying an amino acid to the protein synthetic machinery of a cell as directed by a three-nucleotide sequence in a messenger RNA (mRNA). read more
